The structure of a solution consisting of colloid particles and hydrogen bonding(HB)fluid separated by a semipermeable vesical membrane was investigated. The semipermeable membrane allows the free passage of hydrogen bonding fluid but not colloid particles. Firstly, based on the density functional theory the grand potential of the system and the equilibrium density distribution of the fluids near the membrane were obtained. In addition, the effects of HB energy, HB functionality, bulk fluid density and the size ratio of two species on the local structure were also discussed. It was shown that the equilibrium density and local structure of the two components were closely related to these factors, and it was expected that the present results were helpful to reveal the local structure in the mesoscopic scale and the infiltration of biophysical processes.
